The present invention relates to the field of trackless vehicles and can be used in the construction of passenger cars, can be mounted on trailers.

Known trailer hitch cars described in the book Astelin-Sarkisyanz and Umineko. Trailers for passenger cars. - M.: Transport. 1979 - 79 C. In this case, trailer hitch cars Lada (see this book, p.52, RIS) is a longitudinal beam, rigidly attached to the bottom of the car, equipped with a hitch ball, interacting (see the same book, p.64, RES) with a locking device to secure the ball head by using a wedge mounted on the drawbar of the trailer. Described trailer hitch has a significant disadvantage in that it, first, it is difficult in design and includes, for example, the latch lever pin, lever, cover, spring, wedge, etc. and, secondly, not enough reliable in operation and does not fully meet the safety requirements.

It is also known trailer hitch for cars in patent RU 2230675 C1, which is a ball head, consisting of two parts connected by the finger from the clamp. Despite the simplicity of the design and its effectiveness, PEFC is dnaa also has a significant drawback, namely, that in case of wear of the thread of a threaded sleeve or slice may occur samarasam trailer and car, which can lead to serious consequences on roads with heavy traffic.

Therefore, the aim of the invention is to improve the reliability of the trailer hitch for cars and trailers.

This objective is achieved in that on the inner vertical surface of the circular undercut the upper part of the ball head is made of a circular groove, in cross section having the shape of a semicircle, which in coupled condition of the vehicle and trailer posted by the pair of roller bearings spherical form, also located in the cylindrical passage in the median plane of the circular projection at the lower part of the ball head, and interacting through compression springs and plungers with a cylindrical forming surface of a finger placed in the vertical channels of the upper and lower parts of the ball head.

Figure 1 shows a General view of a combination, figure 2 - part trailer hitch in section, and figure 3 and figure 4 details the ball coupling.

Trailer hitch consists of the upper 1 and lower 2 parts ball head, the first of which is accommodated in the housing 3 of 4 drawbar of the trailer 5, and the second is made in one piece with the bracket 6 trailer hitch AB is mobile 7. On top of the 2 ball head has a circular depression 8 in which the circular groove 9 for the rolling elements are spherical form 10, which is placed in the channel 11 is formed in a circular protrusion 12 of the lower part 2 ball head. The rolling elements are spherical form 10 via compression springs 13 are in contact with the tappets 14 that are in contact with the surface of the finger 15, movably installed in the vertical channels 16 and 17, respectively, belonging to the lower 2 and upper 1 parts ball head. The finger 15 is equipped with technological protrusion 18 with an opening 19, and the casing 3 of 4 drawbar provided with a hole 20 with tube 21.

Works trailer hitch as follows. Figure 1 and figure 2 it is shown in the operating condition, i.e. when the vehicle 7 is in coupling with a trailer 5. For rascepa links trains last set on flat ground and removed from the housing 3 of 4 drawbar tube 21, which may be, for example, made of plastic. Then in the insert hole 19 of Krycek, which may be made of wire, and moving it in direction of the arrow And remove the finger 15 in the same direction of the channels 16 and 17. Remove finger 15 in this direction can be full or so, when the last will contact pushers 14 pressed by the compression spring 13 to its surface. As soon as the finger 15 will be released from the account is the one with the pushers 9, the pressing force of the compression spring 13 on rolling elements are spherical form 10 will weaken, which ultimately will allow the body 3 of 4 drawbar with him also move in the direction of arrow A. Rescap of the vehicle and trailer is completed. For the production of coupling of the above steps must be repeated in reverse order and as soon as the finger 15 will push the pushers 14 on the arrows In the upper 1 and lower 2 parts ball head will be securely fixed relative to each other rolling elements are spherical form 10, which will be placed under the action of the compression spring 13 in a circular groove 9. Next, the processes of rascepa and coupling of the vehicle 7 and the trailer 5 can be repeated.

Feasibility advantage of the proposed technical solutions in comparison with known obviously, because it allows you to secure the place of coupling of the vehicle and the trailer.

Trailer hitch, mainly passenger cars, including the ball head, which consists of two parts - upper and lower mating between a circular protrusion and depression and connected by a finger, characterized in that on the inner vertical surface of the circular depression in the upper part of the ball head is made of a circular groove, in cross section having the shape of a semicircle, in which, in coupled condition of the vehicle and the trailer, posted a pair of roller bearings spherical the shape, also located in the cylindrical passage in the median plane of the circular projection at the lower part of the ball head, and interacting through compression springs and plungers with a cylindrical forming surface of a finger placed in the vertical channels of the upper and lower parts of the ball head.
